You have what is refered to generally as the K4600 series monitor. The 46 in the model number refers to the 4600 series and the 7 refers to mounting bracket style and the 5 refers to what connector it has on the power cord. The manuals for the 4601, 4653, etc. will work for your monitor.
To flip the picture you need to move the wires on the yoke. The 4600 series has push-on terminals which makes it easy. Visit
www.dameon.net/BBBB/yoke.html to get an idea of what to do. Their example uses an Electrohome monitor which has different color wires than other monitor manufacturers use. The 4600 has red & blue for the horizontal so if you move the red wire to where the blue is and the blue to where the red is you'll reverse the left-right orientation (mirror image it). The green & yellow wires are the vertical section. If you move the green to where the yellow is and move the yellow to where the green is you'll flip the picture upside down.
NEVER connect any of the red & blue (horizontal section) to the green & yellow (Vertical section) or vise versa or you'll damage the deflection circuitry of the monitor. Only change the wires around with the
POWER OFF for safety as you are working with high voltage.
